electronic door lock

[Dheera] sent in his electronic door lock. The current version is purely microcontroller based, but I loved this crazy iteration. Seeing something like this evolve is fantastic. I really wanted a keypad door lock when I was old enough to dream of electric sheep.

    Wow, thats pretty cool cause at my work we have these with keypads or using a key but they’re like $150+ bucks. Really cool if u gave it a keypad though too.

    wow!! this is a very different approch :)
    i hope he still carys a key with him ‘cos in the dorms i’ve been in that keyboard would have gone missing one night while i was out late….

    at MIT, that sort of thing is admired, not vandalised. I’m sure it would stay there for quite a long time.

    I go to UMR and made one of these using an old desktop with an unused parallel port. I picked up a cheap RF relay control board, so I don’t have to worry about theft, heh.

    I have to give this guy props, he did a hell of alot more dirty work for this. Also, in case the keyboard did get thefted, what about a web interface?
